| 2015-06-01 | virtio: add explicit big-endian support to memory accessors | Greg Kurz | 1 | -10/+14 | |
| The current memory accessors logic is: - little endian if little_endian - native endian (i.e. no byteswap) if !little_endian If we want to fully support cross-endian vhost, we also need to be able to convert to big endian. Instead of changing the little_endian argument to some 3-value enum, this patch changes the logic to: - little endian if little_endian - big endian if !little_endian The native endian case is handled by all users with a trivial helper. This patch doesn't change any functionality, nor it does add overhead. Signed-off-by: Greg Kurz <[email protected]> Signed-off-by: Michael S.

| 2014-12-09 | virtio: memory access APIs | Michael S. Tsirkin | 1 | -0/+59 | |
| virtio 1.0 makes all memory structures LE, so we need APIs to conditionally do a byteswap on BE architectures. To make it easier to check code statically, add virtio specific types for multi-byte integers in memory. Add low level wrappers that do a byteswap conditionally, these will be useful e.g. for vhost. Add high level wrappers that query device endian-ness and act accordingly. Signed-off-by: Michael S. Tsirkin <[email protected]> Reviewed-by: Cornelia Huck <[email protected]> | |||||
